From what I'm reading I want the 2014 headset to support museIO so I can get direct access to raw data. But, was there anything added to the 2016 version that I'll be missing out on from a developers standpoint? I've looked at the hardware sheet and it just seems to be a change to bluetooth LE, which is actually causing some problems for mac users, so maybe nothing of value? How's battery charge after a few years of use on these?
I'm thinking of buying a used headset off of ebay, I think the distinguishing features on the 2014 headset seem to be that the power button does not have a label and that the muse logo is in grey, vs the 2016 with blue logo and a power icon. Can someone confirm that though?
Thank you for your advice!
